Abstract
A particle detector including a chamber, a first aspirator, a sensor(s), a controller and clean air supply. The controller, when in a detecting mode, receives an indicative signal from the sensor and applies logic to the indicative signal to generate a further signal, and when in the purge mode controls substantial purging of the chamber of sample fluid with clean fluid from the clean fluid supply. The controller receives the indicative signal when the chamber is so purged and if necessary adjusts the logic in response thereto.
